Researchers from the University of California, San Francisco found out that men at age 75 and older with high risks of prostate cancer are treated based on age and not on disease risk.

The group of researchers believes that it should not be the case. According to Dr. Matthew Cooperberg, senior investigator, older men tend to become more at risk because they are under-treated from prostate cancer.

A data from the Journal of Clinical Oncology reveals that if older, high-risk men are treated aggressively, their death rate falls to 46 percent. This is compared to older men who are given conservative treatments.

The group of Cooperberg was able to study men in the Cancer of the Prostate Strategic Urologic Research Endeavor database. This is considered as a longitudinal, observation disease registry of men who are suffering from prostate cancer throughout the United States. The database has 13,805 patient information.
